In the work, if we output the number of the length is fixed, the assumption is 4, if the number is 3, then output 0003, not enough digits in front of the complement of 0, here summed up to provide three different ways to achieve the number of JS code to fill 0 of the operation; The first: the most original way of writing function pad (num, n) { var i = (num + ""). Length; while (i++ The second: the me
